A virtual reality dual use mobile phone case comprises: a casing for fixing the body of a mobile phone; an oculus plate that can maintain a variable distance from a rear surface of the casing; and a screen and distance control member that is arranged between the casing and the oculus plate, and that moves the oculus plate between a contact state in which the oculus plate is in contact with the casing, and a spaced state in which the oculus plate maintains a certain distance from the casing, thereby facilitating implementation of virtual reality.
